Diana Ortiz-Montalvo

Research Chemist


Diana L. Ortiz-Montalvo is a research chemist with the Nano Materials Group in the Materials Measurement Science Division at the National Institute of Standards and Technology (NIST). Diana was born and raised in Puerto Rico, where she earned a B.S. in Chemistry from the University of Puerto Rico, at the Río Piedras Campus (San Juan, PR).  As an undergraduate student, she worked for four years on various research projects that focused on the chemical and physical characterization of atmospheric aerosols. She earned her Ph.D. in Environmental Sciences from Rutgers University (New Brunswick, NJ).  Her doctoral research focused on air pollution science and technology.  As a graduate student, she carefully studied the formation of secondary organic aerosol through simulated cloud chemistry and droplet evaporation experiments. After her Ph.D., she began a two-year postdoctoral position as part of the NRC Research Associateship Program at NIST (Gaithersburg, MD). During her postdoc, she studied the morphology and composition of individual atmospheric particles using advanced microscopy techniques. She also made 3-dimensional reconstructions of those particles to study the effect that particle shape and composition had on their optical properties. Diana continues her research on atmospheric particles and is working on new projects related to particle analysis and characterization.
